Finding solutions to the breakdown chaos is a global rugby priority after the World Cup.
An international group involving All Black coach Steve Hansen initially, then Dave Rennie once his Chiefs work is done, will collect and trial ideas about changes to the complex laws.
Creating space away from suffocating defences and simplifying the confusion at the breakdown have been ongoing research topics for the NZRU as they focus on the shape of rugby after the eighth global tournament finishes in October.
"The breakdown is an area we are clearly focused on because there is a lack of clarity for the fans particularly and probably the players too," said NZRU chief executive Steve Tew.
"When the whistle blows they look up to see who is being penalised, they are never quite sure who it is going to be. That is part of what we are looking at. We are not satisfied with the breakdown but satisfied it needs to remain in the game."
